Descript

• Outcome: Review
• Latest audit: Nov 3, 2026 · 11:54 AM UTC
• Version: 1.0.3

Overview

Descript actions have clear approval safeguards, but setup directs the agent to execute a changeable remote installer without verification or a separate approval step.

Review and approve the CLI installation separately before letting the agent perform setup, including any bundled skill installation or updates. Descript changes already require confirmation. OOMOL mediates account access, so consider its permissions and data handling. The sole bundled artifact was fully inspected; remote installer and connector implementations remain outside that inspection.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Vulnerability Patterns

• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• MCP Tool Poisoning: Hidden Instructions, Unicode Deception, Parameter Description Injection
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration

Findings (3)

Description-Behavior Mismatch

High

• Category: MCP Tool Poisoning
• Confidence: 97% confidence

Finding

The supplied chunk performs remote installer execution and shows no Descript operations or evidence that this installation supports them. This is materially different from the declared Descript data-management purpose. The downloaded script's contents are not supplied, so its further behavior cannot be determined.

Content

No source excerpt is available for this finding.

External Script Fetching

High

• Category: Supply Chain
• Confidence: 98% confidence

Finding

Piping a remotely downloaded script directly into Bash executes its contents with the agent process's local privileges, without a review step or verification against an independently trusted signature or digest. Compromise of the installer distribution could therefore enable local credential theft or arbitrary system changes; the missing-CLI prerequisite reduces exposure but does not remove the risk, and the PowerShell alternative has the same weakness.

Autonomous Decision Making

Medium

• Category: Excessive Agency
• Confidence: 80% confidence

Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
